16-Bit/DOS Suppor Missing?

dwarfcricket · Post by **dwarfcricket** » Mon Jul 12, 2010 3:10 pm

Currently attempting to run an old PC game on my Mac (Leopard). I've installed Wine using MacPorts, which worked flawlessly. Now when I attempt to install my PC Game the terminal responds with "16-Bit/DOS Support missing."

Is there a way to fix this?

Yeah. Run it in DOSBox. You're never going to run that under Wine on a
Mac. That's because the Mac OS X kernel lacks Virtual-8086 mode support.
And it's not trivial to add it, either--especially because most modern
Macs run in 64-bit mode where v86 mode doesn't work.

Well I thought so, too, but when I try to run it in DOS it says "This program requires Microsoft Windows."

Am I doomed? Have all my efforts been futile?

Not to be a pain... but I'm new at this stuff - and that looks like gibberish... i know this is all pretty simple, but I'm just trying to get my footing. So... what should I do with that?

Oh, so it's a Win16 program.

In that case, there are three things you can do:
- Run Windows in a VM, like John suggested. But that requires you to
have a Windows license.
- Upgrade to Snow Leopard. The reason MacPorts builds without Win16
support is that Xcode 3.x has a linker that can't handle 16-bit code
very well. Xcode 3.2, which comes with SL, does not have this problem.
- Patch the linker. See bug 14920
(http://bugs.winehq.org/show_bug.cgi?id=14920 ) for more info.

If you pick one of the last two options, though, you'll then have to
change the Portfile to not pass --disable-win16 to Wine's configure script.

What he thinks you should do is install a virtual machine (like
VirtualBox) or an emulator (like QEMU) and install a version of Windows
(like Win95/98/ME) that has very good support for 16-bit programs. But,
again, that requires a Windows license that you may or may not have.

Well, I don't have a Windows license, unfortunately.

SO, if I were to go about patching it - how would I change the Portfile?

dwarfcricket · Post by **dwarfcricket** » Mon Jul 12, 2010 3:59 pm

ALSO -

If I were to upgrade to Snow Leopard, which I've been meaning to do anyway, could I run this game in DOSBox? Or would I still need to run it with MacPorts/Wine?

The Portfile is in
/opt/local/var/macports/sources/rsync.macports.org/release/ports/x11/wine-devel.
There's a line that reads:

configure.args-append --disable-win16

If you put a pound sign in front:

# configure.args-append --disable-win16

then MacPorts won't disable Win16 support when it builds Wine.

You only need to do this if you patch the linker, though. I just
realized that the Portfile is smart enough to realize when it's on SL.
There, it leaves Win16 support in.

Nope, you still need Wine. (Well, you could run it in DOSBox, but to do
that, you'd need Windows 3.x. You'd need Windows 3.x even on Leopard,
too. And again, you have to have a license to run Windows 3.x.)

Well, I attempted to change the Portfile, but it keeps telling me I don't have the appropriate access to do so - even though my account (I'm the admin) is allowed to Read & Write - is there another way for me to change the settings so that I may change and save the Portfile?

You have to edit the Portfile as root.

'root' is the most powerful user on a Unix-type system. To become root
on Mac OS X, you use the 'sudo' command from the Terminal. (You've used
this command before; you needed it to install Wine from MacPorts in the
first place!) I'm not sure you can run any GUI programs as root, though,
and I definitely wouldn't recommend it, so I suggest using a text editor
like nano or vim or emacs that works in a Terminal.

If you need more help, remember, Google is your friend.

The problem is not 64 bitness, but a broken ld program that came with XCode 3.1. There is a patch to fix this on Wine's Bugzilla and you have to download the source for ld from opensource.apple.com. Also, there is very little truth to the fact that running X86 processors in 64 bit mode disables v86 mode. Maybe Apple disabled this in Snow Leopard, but Vista 64 supports running Win16 programs.

I could swear that you couldn't enter v86 mode when in 64-bit mode. I
seem to remember reading something about that in an early x64 manual I had.

Maybe Apple disabled this in Snow Leopard, but Vista 64 supports running Win16 programs.

That's because you don't need v86 to run most Win16 programs; they run
in 16-bit protected mode (which IS supported even in 64-bit mode).

If I could get your address, I'll email you a patched ld. This would be
for the latest/greatest XCode 3.1 release. However, I highly recommend
upgrading to Snow Leopard, if you can, as it gave me back about 10GB of
hard drive space, and it runs better. Well worth the $29 I spent for
it. It also makes building Wine easier.

Charles Davis little technical fact v86 mode can work with x64 bit OS's but its a trip threw hell of the OS to implement. http://v86-64.sourceforge.net/

There are a few other ugly options that could be implemented including software visualization.

Never is a very long time. If we got a few developers interesting in making wine dos support work without needing v86 it would become possible.

But then again dosbox works quite we so no one is bothered at this stage.
